BACKGROUND

Thymidylate metabolism is required for producing essential building blocks necessary to replicate DNA in dividing cells and has long been an important therapeutic target for cornerstone cancer drugs. Drugs targeting this pathway such as 5-fluorouracil (5-FU) inhibit the enzyme thymidylate synthase (TS) and are currently critical standard-of care therapies. TS-targeted agents are used for the treatment of a variety of cancers including colon, gastric, head and neck, breast, lung and blood related malignancies among others. Grem, J. L., 5-Fluorouracil plus leucovorin in cancer therapy, in Principals and Practice of Oncology Update Series, J. De Vita, V. T., S. Hellman, and A. Rosenberg, Editors. 1988, J. B. Lippincott: Philadelphia, Pa.

There are two classes of drugs that target the TS enzyme: the fluoropyrimidines and the antifolates. The fluoropyrimidines, 5-FU, S-1 and capecitabine (Xeloda®), have wide use in the treatment of gastrointestinal and breast cancers, while the antifolate pemetrexed (Alimta®) is currently used for the treatment of non-small cell lung cancer (NSCLC). Since the discovery of 5-FU over fifty years ago by Charles Heidelberger, the fluoropyrimidines remain one of the most common and effective anticancer cancer drugs used worldwide. Due to this fact, there is an abundance of clinical experience and insight into the mechanism of action of these agents.

The TS inhibitor 5-fluorouracil (5 FU) remains the foundation of many first and second line regimens in the treatment of colon cancer. Single agent therapies including oxaliplatin, irinotecan, Erbitux and Avastin, demonstrate lowered activity in colon cancer compared to 5-FU. In addition to colon cancer, TS-inhibitory agents have demonstrated efficacy in several other solid tumor types. Standard of care now incorporates 5-FU as the backbone drug in combination with oxaliplatin or irinotecan or another agent.

Deoxyuridine triphosphatase (“dUTPase”) is a ubiquitous enzyme that is essential for viability in both prokaryotic and eukaryotic organisms; as the main regulator of dUTP pools, the expression of dUTPase could have profound effects on the utility of chemotherapeutics that inhibit thymidylate biosynthesis. Normally, dUTPase mediates a protective role by limiting the expansion of dUTP pools and countering the cytotoxic effect of uracil misincorporation. According to this model, elevated levels of dUTPase could prevent TS inhibitor-induced dUTP accumulation and induce drug resistance. It has been shown that dUTPase over expression results in a significant decrease in dUTP accumulation and increased resistance to drug treatment when compared to controls.

Chemotherapeutic agents that target de novo thymidylate metabolism are critical for the treatment of a variety of solid tumors, however clinical efficacy is often hindered by drug resistance. Because resistance to these agents is a common occurrence, the identification and exploitation of novel determinants of drug sensitivity within this pathway of proven therapeutic utility is important. As disclosed by Ladner et al. in U.S. Patent Publ. No. US 2011/0212467, the dUTPase enzyme and the uracil-DNA misincorporation pathway can play a driving role in mediating cytotoxicity to TS-directed chemotherapies.

For example, nearly half of cancer patients do not benefit from 5-FU-based treatment due to intrinsic or acquired drug resistance. Due to this fact, there is a critical need to overcome the fundamental challenge of drug resistance and provide new therapeutic strategies to improve patient outcome. This disclosure satisfies this need and provides related advantages as well.

Unless indicated otherwise, the nomenclature of substituents that are not explicitly defined herein are arrived at by naming the terminal portion of the functionality followed by the adjacent functionality toward the point of attachment. For example, the substituent “alkoxycarbonylalkyl” refers to the group (alkoxy)-C(O)-(alkyl)-.

It is understood that in all substituted groups defined above, polymers arrived at by defining substituents with further substituents to themselves (e.g., substituted aryl having a substituted aryl group as a substituent which is itself substituted with a substituted aryl group, etc.) are not intended for inclusion herein. In such cases, the maximum number of such substituents is three. That is to say that each of the above definitions is constrained by a limitation that, for example, substituted aryl groups are limited to -substituted aryl-(substituted aryl)-substituted aryl.

It is understood that the above definitions are not intended to include impermissible substitution patterns (e.g., methyl substituted with 5 fluoro groups). Such impermissible substitution patterns are well known to the skilled artisan.

“Tautomer” refer to alternate forms of a compound that differ in the position of a proton, such as enol-keto and imine-enamine tautomers, or the tautomeric forms of heteroaryl groups containing a ring atom attached to both a ring —NH— moiety and a ring ═N— moiety such as pyrazoles, imidazoles, benzimidazoles, triazoles, and tetrazoles.

Such a moiety provides some or all of the hydrogen bond acceptor-donor-acceptor property of uracil and optionally provides other structural characteristics of uracil. A skilled artisan will further appreciate the meaning of this term by reading the non limiting examples of such uracil isosteres provided herein.

As used herein, the term stereochemically pure denotes a compound which has 80% or greater by weight of the indicated stereoisomer and 20% or less by weight of other stereoisomers. In a further embodiment, the compound of Formula (I), (II), or (III) has 90% or greater by weight of the stated stereoisomer and 10% or less by weight of other stereoisomers. In a yet further embodiment, the compound of Formula (I), (II), or (III) has 95% or greater by weight of the stated stereoisomer and 5% or less by weight of other stereoisomers. In a still further embodiment, the compound of formula (I), (II), or (III) has 97% or greater by weight of the stated stereoisomer and 3% or less by weight of other stereoisomers.

“Pharmaceutically acceptable salt” refers to salts of a compound, which salts are suitable for pharmaceutical use and are derived from a variety of organic and inorganic counter ions well known in the art and include, when the compound contains an acidic functionality, by way of example only, sodium, potassium, calcium, magnesium, ammonium, and tetraalkylammonium; and when the molecule contains a basic functionality, salts of organic or inorganic acids, such as hydrochloride, hydrobromide, tartrate, mesylate, acetate, maleate, and oxalate (see Stahl and Wermuth, eds., “Handbook of Pharmaceutically Acceptable Salts,” (2002), Verlag Helvetica Chimica Acta, Zürich, Switzerland), for a discussion of pharmaceutical salts, their selection, preparation, and use.

Generally, pharmaceutically acceptable salts are those salts that retain substantially one or more of the desired pharmacological activities of the parent compound and which are suitable for in vivo administration. Pharmaceutically acceptable salts include acid addition salts formed with inorganic acids or organic acids. Inorganic acids suitable for forming pharmaceutically acceptable acid addition salts include, by way of example and not limitation, hydrohalide acids (e.g., hydrochloric acid, hydrobromic acid, hydroiodic acid, etc.), sulfuric acid, nitric acid, phosphoric acid, and the like.

Organic acids suitable for forming pharmaceutically acceptable acid addition salts include, by way of example and not limitation, acetic acid, trifluoroacetic acid, propionic acid, hexanoic acid, cyclopentanepropionic acid, glycolic acid, oxalic acid, pyruvic acid, lactic acid, malonic acid, succinic acid, malic acid, maleic acid, fumaric acid, tartaric acid, citric acid, palmitic acid, benzoic acid, 3-(4-hydroxybenzoyl) benzoic acid, cinnamic acid, mandelic acid, alkylsulfonic acids (e.g., methanesulfonic acid, ethanesulfonic acid, 1,2-ethane-disulfonic acid, 2-hydroxyethanesulfonic acid, etc.), arylsulfonic acids (e.g., benzenesulfonic acid, 4-chlorobenzenesulfonic acid, 2-naphthalenesulfonic acid, 4-toluenesulfonic acid, camphorsulfonic acid, etc.), glutamic acid, hydroxynaphthoic acid, salicylic acid, stearic acid, muconic acid, and the like.

Pharmaceutically acceptable salts also include salts formed when an acidic proton present in the parent compound is either replaced by a metal ion (e.g., an alkali metal ion, an alkaline earth metal ion, or an aluminum ion) or by an ammonium ion (e.g., an ammonium ion derived from an organic base, such as, ethanolamine, diethanolamine, triethanolamine, morpholine, piperidine, dimethylamine, diethylamine, triethylamine, and ammonia).

An “effective amount” is an amount sufficient to effect beneficial or desired results. An effective amount can be administered in one or more administrations, applications or dosages. Such delivery is dependent on a number of variables including the time period for which the individual dosage unit is to be used, the bioavailability of the therapeutic agent, the route of administration, etc. It is understood, however, that specific dose levels of the therapeutic agents disclosed herein for any particular subject depends upon a variety of factors including the activity of the specific compound employed, bioavailability of the compound, the route of administration, the age of the animal and its body weight, general health, sex, the diet of the animal, the time of administration, the rate of excretion, the drug combination, and the severity of the particular disorder being treated and form of administration. In general, one will desire to administer an amount of the compound that is effective to achieve a serum level commensurate with the concentrations found to be effective in vivo. These considerations, as well as effective formulations and administration procedures are well known in the art and are described in standard textbooks.

“Therapeutically effective amount” of a drug or an agent refers to an amount of the drug or the agent that is an amount sufficient to obtain a pharmacological response such as inhibiting dUTPase; or alternatively, is an amount of the drug or agent that, when administered to a patient with a specified disorder or disease, is sufficient to have the intended effect, e.g., treatment, alleviation, amelioration, palliation or elimination of one or more manifestations of the specified disorder or disease in the patient. A therapeutic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses. Thus, a therapeutically effective amount may be administered in one or more administrations.

As used herein, “treating” or “treatment” of a disease in a patient refers to (1) preventing the symptoms or disease from occurring in an animal that is predisposed or does not yet display symptoms of the disease; (2) inhibiting the disease or arresting its development; or (3) ameliorating or causing regression of the disease or the symptoms of the disease. As understood in the art, “treatment” is an approach for obtaining beneficial or desired results, including clinical results. For the purposes of this technology, beneficial or desired results can include one or more, but are not limited to, alleviation or amelioration of one or more symptoms, diminishment of extent of a condition (including a disease), stabilized (i.e., not worsening) state of a condition (including disease), delay or slowing of condition (including disease), progression, amelioration or palliation of the condition (including disease), states and remission (whether partial or total), whether detectable or undetectable.

“dUTPase” means any of the following, which are considered to be synonymous, “deoxyuridine triphosphate nucleotidohydrolase”, “deoxyuridine triphosphate pyrophosphatase”, “dUTP nucleotidohydrolase”, “dUTP pyrophosphatase”, and other equivalent nomenclature for the dUTPase enzyme. In one aspect, dUTPase intends DUT-N and DUT-M. In other aspects, it is DUT-N only, or alternatively, DUT-M only. The amino acid and coding sequences for dUTPase are known in the art and disclosed in U.S. Pat. No. 5,962,246. Methods for expressing and screening for expression level of the enzyme are disclosed in U.S. Pat. No. 5,962,246 and Ladner et al. (US Patent Publ. No. 2011/0212467A1).

“DUT-N” means the nuclear form of dUTPase.

“DUT-M” means the mitochondrial or cytoplasmic form of dUTPase.

“dUTPase-directed therapy” intends therapeutics that target the dUTPase pathway, e.g., in the case of cancer, e.g. TS-directed therapies and the fluoropyrimidines (such as 5-FU), pemetrexed (Alimta®), capecitabine (Xeloda®), S-1 and antifolates (such as methotrexate) and chemical equivalents thereof. Non-limiting examples include 5-flurouracil (5-FU), TS-directed therapies and 5-FU based adjuvant therapy. Combination therapies can include any intervention that alters nucleotide pools and/or sensitizes the immune cells or viruses to the dUTPase inhibitor, as are well known to the skilled artisan. For rheumatoid arthritis, for example, the combination can be with an dihydrofolate reductase (DHFR) inhibitor such as methotrexate.

5-fluorouracil (5-FU) belongs to the family of therapy drugs called pyrimidine based anti-metabolites. It is a pyrimidine analog, which is transformed into different cytotoxic metabolites that are then incorporated into DNA and RNA thereby inducing cell cycle arrest and apoptosis. Chemical equivalents are pyrimidine analogs which result in disruption of DNA replication. Chemical equivalents inhibit cell cycle progression at S phase resulting in the disruption of cell cycle and consequently apoptosis. Equivalents to 5-FU include prodrugs, analogs and derivative thereof such as 5′-deoxy-5-fluorouridine (doxifluoroidine), 1-tetrahydrofuranyl-5-fluorouracil (ftorafur), capecitabine (Xeloda®), S-1 (MBMS-247616, consisting of tegafur and two modulators, a 5-chloro-2,4-dihydroxypyridine and potassium oxonate), ralititrexed (tomudex), nolatrexed (Thymitaq, AG337), LY231514 and ZD9331, as described for example in Papamicheal (1999) The Oncologist 4:478-487.

“5-FU based adjuvant therapy” refers to 5-FU alone or alternatively the combination of 5-FU with other treatments, that include, but are not limited to radiation, methyl-CCNU, leucovorin, oxaliplatin, irinotecin, mitomycin, cytarabine, levamisole. Specific treatment adjuvant regimens are known in the art as FOLFOX, FOLFOX4, FOLFIRI, MOF (semustine (methyl-CCNU), vincrisine (Oncovin®) and 5-FU). For a review of these therapies see Beaven and Goldberg (2006) Oncology 20(5):461-470. An example of such is an effective amount of 5-FU and Leucovorin. Other chemotherapeutics can be added, e.g., oxaliplatin or irinotecan.

Capecitabine is a prodrug of (5-FU) that is converted to its active form by the tumor-specific enzyme PynPase following a pathway of three enzymatic steps and two intermediary metabolites, 5′-deoxy-5-fluorocytidine (5′-DFCR) and 5′-deoxy-5-fluorouridine (5′-DFUR). Capecitabine is marketed by Roche under the trade name Xeloda®.

Leucovorin (Folinic acid) is an adjuvant used in cancer therapy. It is used in synergistic combination with 5-FU to improve efficacy of the chemotherapeutic agent. Without being bound by theory, addition of Leucovorin is believed to enhance efficacy of 5-FU by inhibiting thymidylate synthase. It has been used as an antidote to protect normal cells from high doses of the anticancer drug methotrexate and to increase the antitumor effects of fluorouracil (5-FU) and tegafur-uracil. It is also known as citrovorum factor and Wellcovorin. This compound has the chemical designation of L-Glutamic acid N[4[[(2-amino-5-formyl 1,4,5,6,7,8hexahydro4oxo6-pteridinyl)methyl]amino]b-enzoyl], calcium salt (1:1).

“Oxaliplatin” (Eloxatin) is a platinum-based chemotherapy drug in the same family as cisplatin and carboplatin. It is typically administered in combination with fluorouracil and leucovorin in a combination known as FOLFOX for the treatment of colorectal cancer. Compared to cisplatin, the two amine groups are replaced by cyclohexyldiamine for improved antitumour activity. The chlorine ligands are replaced by the oxalato bidentate derived from oxalic acid in order to improve water solubility. Equivalents to Oxaliplatin are known in the art and include, but are not limited to cisplatin, carboplatin, aroplatin, lobaplatin, nedaplatin, and JM-216 (see McKeage et al. (1997) J. Clin. Oncol. 201:1232-1237 and in general, Chemotherapy for Gynecological Neoplasm, Curr. Therapy and Novel Approaches, in the Series Basic and Clinical Oncology, Angioli et al. Eds., 2004).

“FOLFOX” is an abbreviation for a type of combination therapy that is used to treat cancer. This therapy includes 5-FU, oxaliplatin and leucovorin. “FOLFIRI” is an abbreviation for a type of combination therapy that is used treat cancer and comprises, or alternatively consists essentially of, or yet further consists of 5-FU, leucovorin, and irinotecan. Information regarding these treatments are available on the National Cancer Institute's web site, cancer.gov, last accessed on Jan. 16, 2008.

Irinotecan (CPT-11) is sold under the trade name of Camptosar. It is a semi-synthetic analogue of the alkaloid camptothecin, which is activated by hydrolysis to SN-38 and targets topoisomerase I. Chemical equivalents are those that inhibit the interaction of topoisomerase I and DNA to form a catalytically active topoisomerase I-DNA complex. Chemical equivalents inhibit cell cycle progression at G2-M phase resulting in the disruption of cell proliferation.

The term “adjuvant” therapy refers to administration of a therapy or chemotherapeutic regimen to a patient after removal of a tumor by surgery. Adjuvant therapy is typically given to minimize or prevent a possible cancer reoccurrence. Alternatively, “neoadjuvant” therapy refers to administration of therapy or chemotherapeutic regimen before surgery, typically in an attempt to shrink the tumor prior to a surgical procedure to minimize the extent of tissue removed during the procedure.

The phrase “first line” or “second line” or “third line” etc., refers to the order of treatment received by a patient. First line therapy regimens are treatments given first, whereas second or third line therapy are given after the first line therapy or after the second line therapy, respectively. The National Cancer Institute defines first line therapy as “the first treatment for a disease or condition. In patients with cancer, primary treatment can be surgery, chemotherapy, radiation therapy, or a combination of these therapies. First line therapy is also referred to those skilled in the art as primary therapy and primary treatment.” See National Cancer Institute website as www.cancer.gov, last visited on May 1, 2008. Typically, a patient is given a subsequent chemotherapy regimen because the patient did not shown a positive clinical or sub-clinical response to the first line therapy or the first line therapy has stopped.

As used herein, the term “antifolate” intends a drug or biologic that impairs the function of folic acids, e.g., an antimetabolite agent that inhibits the use of a metabolite, i.e. another chemical that is part of normal metabolism. In cancer treatment, antimetabolites interfere with DNA production, thus cell division and growth of the tumor. Non-limiting examples of these agents are dihydrofolate reductase inhibitors, such as methotrexate, Aminopterin, and Pemetrexed; thymidylate synthase inhibitors, such as Raltitrexed or Pemetrexed; purine based, i.e. an adenosine deaminase inhibitor, such as Pentostatin, a thiopurine, such as Thioguanine and Mercaptopurine, a halogenated/ribonucleotide reductase inhibitor, such as Cladribine, Clofarabine, Fludarabine, or a guanine/guanosine: thiopurine, such as Thioguanine; or Pyrimidine based, i.e. cytosine/cytidine: hypomethylating agent, such as Azacitidine and Decitabine, a DNA polymerase inhibitor, such as Cytarabine, a ribonucleotide reductase inhibitor, such as Gemcitabine, or a thymine/thymidine: thymidylate synthase inhibitor, such as a Fluorouracil (5-FU).

In one aspect, the term “chemical equivalent” means the ability of the chemical to selectively interact with its target protein, DNA, RNA or fragment thereof as measured by the inactivation of the target protein, incorporation of the chemical into the DNA or RNA or other suitable methods. Chemical equivalents include, but are not limited to, those agents with the same or similar biological activity and include, without limitation a pharmaceutically acceptable salt or mixtures thereof that interact with and/or inactivate the same target protein, DNA, or RNA as the reference chemical.

The terms “oligonucleotide” or “polynucleotide” or “portion,” or “segment” thereof refer to a stretch of polynucleotide residues which is long enough to use in PCR or various hybridization procedures to identify or amplify identical or related parts of mRNA or DNA molecules. The polynucleotide compositions of this invention include RNA, cDNA, genomic DNA, synthetic forms, and mixed polymers, both sense and antisense strands, and may be chemically or biochemically modified or may contain non-natural or derivatized nucleotide bases, as will be readily appreciated by those skilled in the art. Such modifications include, for example, labels, methylation, substitution of one or more of the naturally occurring nucleotides with an analog, internucleotide modifications such as uncharged linkages (e.g., methyl phosphonates, phosphotriesters, phosphoamidates, carbamates, etc.), charged linkages (e.g., phosphorothioates, phosphorodithioates, etc.), pendent moieties (e.g., polypeptides), intercalators (e.g., acridine, psoralen, etc.), chelators, alkylators, and modified linkages (e.g., alpha anomeric nucleic acids, etc.). Also included are synthetic molecules that mimic polynucleotides in their ability to bind to a designated sequence via hydrogen bonding and other chemical interactions. Such molecules are known in the art and include, for example, those in which peptide linkages substitute for phosphate linkages in the backbone of the molecule.

When a genetic marker, e.g., over expression of dUTPase, is used as a basis for selecting a patient for a treatment described herein, the genetic marker is measured before and/or during treatment, and the values obtained are used by a clinician in assessing any of the following: (a) probable or likely suitability of an individual to initially receive treatment(s); (b) probable or likely unsuitability of an individual to initially receive treatment(s); (c) responsiveness to treatment; (d) probable or likely suitability of an individual to continue to receive treatment(s); (e) probable or likely unsuitability of an individual to continue to receive treatment(s); (f) adjusting dosage; (g) predicting likelihood of clinical benefits; or (h) toxicity. As would be well understood by one in the art, measurement of the genetic marker in a clinical setting is a clear indication that this parameter was used as a basis for initiating, continuing, adjusting and/or ceasing administration of the treatments described herein.

“Cancer” is a known medically as a malignant neoplasm, is a broad group of diseases involving unregulated cell growth. In cancer, cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. Non-limiting examples include colon cancer, colorectal cancer, gastric cancer, esophogeal cancer, head and neck cancer, breast cancer, lung cancer, stomach cancer, liver cancer, gall bladder cancer, or pancreatic cancer or leukemia.

The methods comprise, or alternatively consist essentially of, or yet further consist of, contacting the dUTPase with a therapeutically effective amount of the compound or composition as disclosed herein. In one embodiment, the methods further comprise, or alternatively consist essentially of, or yet further consist of, contacting the dUTPase with an effective amount of a dUTPase-directed therapy. In one aspect, the contacting of the dUTPase-directed therapy is prior to, concurrent or subsequent to contacting with the compound or composition of this disclosure.

One of skill in the art can also determine if the compound or combination inhibits dUTPase in vitro by contacting the compound or combination with purified or recombinant dUTPase in a cell free system. The purified or recombinant dUTPase and can be from any species, e.g., simian, canine, bovine, ovine, rat, mouse or human. In one aspect, the dUTPase is DUT-N or DUT-M. Isolation, characterization and expression of dUTPase isoforms are disclosed in U.S. Pat. No. 5,962,246 and known in the art.

The contacting can be performed cell-free in vitro or ex vivo with a cell or in a cell culture. When performed in vitro or ex vivo, the compounds, compositions or agents can be directly added to the enzyme solution or added to the cell culture medium. When practiced in vitro or ex vivo, the method can be used to screen for novel combination therapies, formulations or treatment regimens, prior to administration to administration to an animal or a human patient. Methods to quantify inhibition are known in the art, see, U.S. Patent Publ. Nos. 2010/0075924 and 2011/0212467 and U.S. Pat. No. 7,601,702. For example, a fixed dose of a dUTPase directed therapy (e.g., 5-FU or Pemetrexed) can be added to the system and varying amounts of the compound can be subsequently added to system. Alternatively, a fixed dose of a compound of this invention can be added to the system and varying amounts of the dUTPase directed therapy (e.g., 5-FU or Pemetrexed) compound can be subsequently added to system.

In one aspect, the contacting is ex vivo and the cell or tissue to be contacted over expresses dUTPase. These cells can be isolated from a patient prior to administration to the patient or can be purchased from a depository such as the American Type Culture Collection (ATCC). Non-limiting examples of animal (e.g., canine, an equine, a bovine, a feline, an ovine, a mouse, a rat or a simian) and human cells that are known to over express dUTPase include, without limitation cancer cells, e.g. colon cancer, colorectal cancer, gastric cancer, head and neck cancer, breast cancer, stomach cancer or lung cancer. The cancer can be metastatic or non-metastatic. Methods to quantify inhibition are known in the art, see, U.S. Patent Publ. Nos. 2010/0075924 and 2011/0212467 and U.S. Pat. No. 7,601,702 and Wilson et al. (2012) Mol. Cancer Ther. 11:616-628.

When practiced in vivo in a patient such as an animal or human, the compounds, compositions or agents are administered in an effective amount by a suitable route of administration, as determined by a treating physician taking into account the patient, disease and other factors. When practiced in a non-human animal, e.g., an appropriate mouse model, the method can be used to screen for novel combination therapies, formulations or treatment regimens, prior to administration to a human patient.

This disclosure also provides methods of treating a disease whose treatment is impeded by the expression of dUTPase, comprising, or alternatively consisting essentially of, or yet further consisting of, administering to a patient in need of such treatment a therapeutically effective amount of the compound or composition of this disclosure, thereby treating the disease. In one aspect, the method further comprises isolating a cell or tissue sample from the patient and screening for the expression level of dUTPase, wherein over expression of dUTPase in the sample as compared to a control sample serves as a basis for selecting the patient as suitable for the method and therapies. Methods to quantify dUTPase are known in the art. Effective amounts will vary with the patient, the disease and the general health of the patient and are determined by the treating physician. Methods to quantify inhibition are known in the art, see, U.S. Patent Publ. Nos. 2010/0075924 and 2011/0212467 and U.S. Pat. No. 7,601,702 and Wilson et al. (2012) Mol. Cancer Ther. 11:616-628. If the patient sample shows over expression of dUTPase, the therapy is administered to the patient. If the patient sample does not show over expression, an alternate therapy is chosen. The screen can be repeated throughout therapy as a means to monitor the therapy and/or dosage regimen.

To practice this method, the sample is a patient sample containing the tumor tissue, normal tissue adjacent to said tumor, normal tissue distal to said tumor or peripheral blood lymphocytes. In a further aspect, the patient or patient population to be treated also is treatment naïve.

For example, one of skill in the art can also determine if the compound or combination inhibits dUTPase in vitro by contacting the compound or combination with purified or recombinant dUTPase in a cell free system. The purified or recombinant dUTPase and can be from any species, e.g., simian, canine, bovine, ovine, rat, mouse or human. In one aspect, the dUTPase is DUT-N or DUT-M. Isolation, characterization and expression of dUTPase isoforms are disclosed in U.S. Pat. No. 5,962,246 and known in the art.

The contacting can be performed cell-free in vitro or ex vivo with a cell or in a cell culture. When performed in vitro or ex vivo, the compounds, compositions or agents can be directly added to the enzyme solution or added to the cell culture medium. When practiced in vitro or ex vivo, the method can be used to screen for novel combination therapies, formulations or treatment regimens, prior to administration to administration to an animal or a human patient. Methods to quantify inhibition are known in the art, see, U.S. Patent Publ. Nos. 2010/0075924 and 2011/0212467 and U.S. Pat. No. 7,601,702. For example, a fixed dose of a dUTPase directed therapy (e.g., 5-FU or Pemetrexed) can be added to the system and varying amounts of the compound can be subsequently added to system. Alternatively, a fixed dose of a compound of this invention can be added to the system and varying amounts of the dUTPase directed therapy (e.g., 5-FU or Pemetrexed) compound can be subsequently added to system.

In another aspect, the assay requires contacting a first sample comprising suitable cells or tissue (“control sample”) with an effective amount of a composition of this invention and optionally a dUTPase inhibitor, and contacting a second sample of the suitable cells or tissue (“test sample”) with the agent to be assayed and optionally a dUTPase inhibitor. In one aspect, the cell or tissue over express dUTPase. The inhibition of growth of the first and second cell samples are determined. If the inhibition of growth of the second sample is substantially the same or greater than the first sample, then the agent is a potential drug for therapy. In one aspect, substantially the same or greater inhibition of growth of the cells is a difference of less than about 1%, or alternatively less than about 5% or alternatively less than about 10%, or alternatively greater than about 10%, or alternatively greater than about 20%, or alternatively greater than about 50%, or alternatively greater than about 90%. The contacting can be in vitro or in vivo. Means for determining the inhibition of growth of the cells are well known in the art.

In a further aspect, the test agent is contacted with a third sample of cells or tissue comprising normal counterpart cells or tissue to the control (or alternatively cells that do not over express dUTPase) and test samples and selecting agents that treat the second sample of cells or tissue but does not adversely effect the third sample.

Biological Methods

A. Drugs, Reagents and Cell Lines

Test compounds are suspended in DMSO at a concentration, e.g., of 100 mmol/L, fluorodeoxyuridine (FUdR) that can be obtained from Sigma (St Louis, Mo.) and maintained in sterile double-distilled water at stock concentrations of 50 mmol/L.

Recombinant human deoxyuridine nucleotidohydrolase (dUTPase) is expressed and purified as described in Ladner R D, Carr S A, Huddleston M J, McNulty D E, Caradonna S J. J Biol Chem. 1996 Mar. 29; 271(13):7752-7. All drugs stocks are aliquoted and diluted as appropriate prior to use. The oligonucelotide primer, templates and fluorophore- and quencher-labeled detection probes are synthesized by Integrated DNA Technologies (Coralville, Iowa), subjected to polyacrylamide gel electrophoresis purification and reconstituted in Omnipur sterile nuclease-free water (EMD Chemicals USA, Gibbstown N.J.) at a stock concentration of 100 μmol/L. The two non-emissive (dark) quenching molecules incorporated into the detection probes include the Iowa black fluorescein quencher (IBFQ; absorption max 531 nm) and ZEN (non-abbreviation; absorption max 532 nm). The fluorescent label utilized is 6-FAM (5′-carboxyfluorescein; excitation max.=494 nm, emission max.=520 nm). Probes are further diluted to a working stock of 10 μmol/L and aliquoted to avoid repeated freeze/thaw cycles. AmpliTaq Gold DNA Polymerase, GeneAmp 10×PCR Buffer 2, MgCl₂ and MicroAmp Optical 96-well Reaction Plates are purchased from Applied Biosystems (Carlsbad, Calif.). dNTPs are purchased individually at stock concentrations of 100 mmol/L from New England Biolabs at HPLC-certified >99% purity (Ipswich, Mass.).

B. Assay Components, Instrumentation and Real-Time Fluorescence Conditions

Reaction mixtures contained primer, probe and template at an equimolar final concentration of 0.4 μmol/L. Magnesium chloride (MgCl₂) is included at a final concentration of 2 mmol/L. Non-limiting dNTPs are included in the reaction mix in excess at a final concentration of 100 μmol/L (dUTP/dTTP is excluded). AmpliTaq Gold DNA polymerase is added at 0.875 U/reaction, 2.5 μl of 10×PCR buffer 2 added and nuclease-free ddH₂O added to a final reaction volume of 25 μl. For dUTP inhibition analysis, the volume of ddH₂O is further modified to accommodate an additional 1 μl of dUTPase (10 ng/μl) and 1 μl of inhibitor or DMSO control. Thermal profiling and fluorescence detection is performed using the ‘isothermal’ program on board an Applied Biosystems 7500 Real-Time PCR System. For analysis of dNTPs, the thermal profile consisted of an 8 min 37° C. step followed by a 10 min 95° C. step to ‘hot-start’ the Taq polymerase and a primer extension time of up to 30 min at 60° C. depending on the application. Raw fluorescence spectra for 6-FAM is measured using filter A at specified time intervals to follow assay progression using Sequence Detection Software (SDS Version 1.4, Applied Biosystems) and exported and analyzed in Microsoft Excel (Microsoft, Redmond Wash.) and Prism (GraphPad Software, La Jolla Calif.). Fluorescence values for blank reactions (limiting dNTP omitted) are subtracted to give normalized fluorescence units (NFU) to account for background fluorescence.

C. MTS Growth Inhibition Assay

The Cell Titer AQueous MTS assay (Promega) is carried out according to the manufacturers guidelines. IC_(50(72h)) values are calculated from sigmoidal-dose response curves utilizing Prism (Graphpad, San Diego, Calif.). The combination effect is determined by the combination index (CI) method utilizing Calcusyn software (Biosoft, Ferguson, Mo.). Fraction affected (FA) is calculated from the percent growth inhibition: FA=(100-% growth inhibition)/100. CI values <1, synergism; 1-1.2, additive and >1.2, antagonism.

D. Colony Formation Assay

Colony forming assay showing the ability of colon (SW620, HCT116), non-small cell lung (A549, H460, H1299 and H358) and breast (MCF7) cancer cells to survive and proliferate following transient 24 hour exposure to test compounds, FUdR and combinations are determined. Specifically, cells are seeded at densities between 50 and 100 cells/well in 24-well plates. Twenty-four hours later, cells are treated with increasing concentrations of a rtest compound, a fixed dose of FUdR and combinations of these. After 24 hours, drug is removed, cells are rinsed and allowed to outgrow for 10-14 days. At the conclusion of the outgrowth, cells are fixed in 60% ice cold methanol and stained with 0.1% crystal violet, scanned and counted. Data is presented as percentage of untreated controls (mean±SD). Fraction affected and combination indexes are calculated according to the method of Chou and Talalay where <1 is indicative of a synergistic drug interaction.

E. In vivo Analysis

Xenograft experiments are conducted in male NU/NU nude mice (Charles River, Wilmington, Mass.) that are 6-8 weeks old. Subcutaneous A549 xenografts are established and allowed to grow until they reached ˜50 mm³ (day 1). Animals are randomized to treatment groups: vehicle, pemetrexed 50 mg/kg, a test compound and combination of pemetrexed plus a test compound (n=5, group). Pemetrexed is administered at 50 mg/kg by intraperitoneal injection every two days. Test compound is administered, e.g., at 75 mg/kg by intraperitoneal injection every two days. The combination of pemetrexed and the test compound is administered by intraperitoneal injection, e.g., every two days. Two perpendicular diameters of tumors are measured every 2 days with a digital caliper by the same investigator. Tumor volume is calculated according to the following formula: TV (mm³)=(length[mm]×(width[mm]²)/2. Mice are inspected everyday for overall health and bodyweight is measured every 2 days as an index of toxicity. All animal protocols are approved by the USC Institutional Animal Care and Use Committee (IACUC).

dUTPase Inhibition

Test compounds are screened in a fluorescence-based assay. The assay employs a DNA polymerase-based approach utilizing an oligonucleotide template with 3 distinct regions: a 3′ primer binding region, a mid-template dUTP/thymidine triphosphate (TTP) detection region and a 5′ 6-Flavin adenine mononucleotide (FAM)-labeled probe binding region that incorporates a black hole quenching moiety. During the reaction, the probe and primer hybridize to the oligonucleotide template to form the template:primer:probe complex. When Taq polymerase binds to the primer in the TPP complex and dUTP is present, successful extension of the nascent strand occurs and the inherent 5′ to 3′ exonuclease activity of Taq polymerase cleaves and displaces the 6-FAM-labeled probe in a 5′ to 3′ direction, releasing the 6-FAM fluorophore from its proximity to the three quenchers. This displacement effectively disrupts the Förster resonance energy transfer (FRET) and the resulting fluorescence detected upon excitation is directly proportional to the amount of the dUTP available in the assay for incorporation. Conversely, when the dUTP is unavailable, exhausted, or degraded by dUTPase and is no longer available for incorporation, Taq polymerase stalls and extension delay and/or chain termination of the nascent strand occurs. In this instance, probe hydrolysis/degradation does not occur and the probe remains dark as fluorescence remains quenched via FRET. Since fluorescence is directly proportional to the concentration of dUTP, the assay is easily modified to measure dUTP and the effects of inhibitors on dUTP hydrolysis by the enzyme dUTPase. The template BHQ-DT6 (Black Hole Quencher—Detection Template 6) for detecting up to 60 pmols of dUTP is included for this application of the assay along with 50 pmols of dUTP and 5 ng of recombinant dUTPase. The reaction is incubated at 37° C. for 8 mins and terminated by a 10 min incubation at 95° C. to simultaneously inactivate dUTPase and activate the hot-start Taq polymerase. The fluorescence generated during the detection step is directly proportional to the concentration of dUTP remaining after the 8 min incubation. The concentration of dUTP at reaction termination and therefore inhibition of dUTPase in the presence and absence of inhibitors and appropriate dimethyl sulfoxide (DMSO) controls can be determined.

Test compounds are evaluated for their antitumor activity in colorectal cancer cells using the MTS growth inhibition assay. HCT116 and SW620 cells are exposed to increasing concentrations of each agent for 72 hours and growth inhibition is directly compared to vehicle-treated controls. The NSCLC cell lines A549 and H1299 are exposed to increasing concentrations of each agent for 72 hours and growth inhibition is directly compared to vehicle-treated controls.

Growth Inhibition

MTS growth inhibition assays are performed to evaluate the effectiveness of the tyest compounds alone and in combination with the fluoropyrimidine thymidylate synthase (TS) inhibitor 5-fluorouracil (5-FU) at inhibiting the growth of colorectal (HCT116 and SW620) cell line models. Increasing concentrations of 5-FU between 0 and 100 μmol/L demonstrated dose-dependent increases in growth inhibition in both the colorectal cancer cell lines evaluated. Simultaneous treatment with increasing concentrations of 5-FU and a test compound at fixed concentrations of 25 μmol/L is determined.

Reducing Cancer Cell Viability

Colony forming assays are performed to evaluate the effectiveness of test compounds alone and in combination with the fluoropyrimidine thymidylate synthase (TS) inhibitor fluorodeoxyuridine (FUdR) at reducing cancer cell viability in colorectal (HCT116), breast (MCF-7) and non-small cell lung (H1299, A549, H358 and H460) cell line models. Increasing concentrations of FUdR between 0.5 and 2.5 μmol/L demonstrated dose-dependent decreases in colonies formed in all cell lines evaluated. In colorectal cancer cells, concentrations of test compounds ranging e.g., from 3.1 μmol/L to 50 μmol/L are combined with 0.5 μl mol/L FUdR in HCT116 cells and 1 μl mol/L FUdR in SW620 cells.
